1. Potassium carbonate can be used to produce optical glass, which can improve glass transparency, strength, and refractive index.
2. It is also used in the production of welding electrodes to prevent arc breakage during welding.
3. Used for the production of vat dyes and their printing and dyeing, as well as for the whitening of ice dyeing.
4. Used as an adsorbent for removing hydrogen sulfide and carbon dioxide.
5. Potassium carbonate mixed with soda ash can be used as a dry powder fire extinguishing agent.
6. It can also be used as an auxiliary raw material for acetone and alcohol production, as well as an anti-aging agent in rubber production.
7. Potassium carbonate aqueous solution can be used for the cooking and refining of cotton fabrics and the defatting of wool.
8. It is also used in the production of inks, photographic pharmaceuticals, polyester, pharmaceuticals, electroplating, leather making, ceramics, building materials, crystals, potassium soap, and pharmaceuticals.
9. Heavy potassium carbonate is mainly used as a raw material for picture tube glass shells, widely used in glass and special glass materials, and used for decarbonization of large chemical fertilizers.
10. Can be used as a leavening agent in food.
